Unfortunately, I don't have direct access to the content of images, diagrams, or specific identifiers like "1340274" or "1358540" that you're referring to in your questions. Therefore, I'm unable to view graphs or images. However, I'll provide answers based on typical interpretations of such questions where possible.
Question 1: b - If the graph is a straight line, it typically means the object moves at a constant speed.
Question 2: a - Unbalanced forces cause the motion of an object to change.
Question 3: Without seeing the diagram, it's impossible to determine which box has the most mass. The one with the largest reading on the spring scale would have the most mass.
Question 4: Without seeing the graph, I cannot provide an accurate answer to what it represents. However, if the graph is a straight line at an angle, it would indicate constant velocity (c); if it's a curved line upward, it could indicate constant (a) or increasing acceleration (b); if it's a straight horizontal line, it would indicate zero linear velocity (c3 from Column B).
Question 5: b - If Ethan has to push harder, it indicates that table A has more mass than table B.
Question 6: d - The net force should be calculated by adding the forces since they are in the same direction.
Question 7: d - Acceleration is the rate at which an object changes its velocity.
Question 8: b - Newton's first law of motion is also known as the law of inertia.
Question 9: Without seeing the picture or knowing the actual weights, I cannot determine which ball would require the most force to lift. However, in general, it would be the ball with the greatest mass (which is not necessarily related to size or material).
Question 10: c - The motorcycle and the car have the same speed but different velocities (since velocity also considers direction).
Question 11: b - Velocity is a vector quantity that includes both speed and direction, which is provided in "10 km/hr eastward."
Question 12: c - If the flag is not moving, it suggests that Victoria and Claire are applying equal forces in opposite directions.
Question 13: Without seeing the respective graphs, I'm unable to match them to the types of motion described. However, usually:
1. A horizontal line would match to c. zero linear velocity.
2. A straight sloping line upwards would match to b. positive linear velocity.
3. A curved line sloping upwards more and more steeply would match to d. increasing, nonlinear velocity.
4. A curved line sloping downwards would match to a. decreasing, nonlinear velocity.
Question 14: Again, without seeing the graphs I can't provide an accurate answer. However, typically a horizontal line on a distance vs. time graph represents constant speed.
Question 15: As I cannot see the graph "1358540" referred to, I can't describe the acceleration. The type of curve on a velocity vs. time graph would provide this information.
Question 16: b - To find out the speed of each boat in a race, besides the distance, you would need the time it takes each boat to finish the race. Speed is distance divided by time.
When answering questions involving visuals or specific diagrams, having the ability to view the associated material is crucial for accuracy. If you can provide more descriptive detail or context for questions that reference images or graphs, I can give more precise answers.
